摘  要:
本研究利用SAS 8.1软件的最小二乘方差分析和MTDFREML软件对南山种羊场的2125只中国美利奴羊(新疆型)的初生重进行了遗传力估计,并分析了非遗传因素对羔羊初生重的影响。结果表明,初生重的遗传力为0.30,属于中等遗传力(0.10.05)。试验结果为中国美利奴羊(新疆型)进一步选育提供一定的依据。

摘  要:
The article estimate the heritability and analysis the influence of non-genetic factors on birth weight of the number of 2125Chinese Merino sheep(Xinjiang type)by using SAS 8.1program of least-squares analysis and MTDFREML software,the data collected from Nanshan sheep breeding farm.The results showed that the birth weight heritability of Chinese Merino sheep was 0.30,it belonged to the moderate heritability(0.10.05).
